## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability dripstack-publications-003b3cc4
```

Example prompt: What Substack publications does DripStack have available — show me the full list with their slugs and site URLs so I can pick one to pull posts from.

## When to prefer this

Use this endpoint as a discovery step before fetching posts or content from a specific Substack publication via DripStack — it gives you the canonical slugs and URLs needed to identify which publication to query next. Prefer this when you need to enumerate all available publications rather than searching for a specific one.

## Known failure modes

- Empty publications array if no publications are indexed yet
- Network timeout if DripStack service is unavailable
- 500 server error if the backend is experiencing issues

## How this service works

List curated newsletters, podcasts, and publications.

## Output

Returns a JSON object with a 'publications' array, where each entry includes a slug (string), siteUrl (string), and optionally title, description, and lastSyncedAt timestamp indicating when DripStack last synced that publication.
